Many countries around the world are facing severe challenges due to recently emerging variants of SARS-CoV-2. Over last few months, scientists have been developing treatments, drugs, and vaccines subdue virus prevent its transmission. In this context, a peptide-based vaccine construct containing pathogenic proteins known elicit an immune response was constructed. An analysis spike protein-based epitopes allowed us design "epitope-based subunit vaccine" against coronavirus using approaches...

Alzheimer's disease (AD) is a type of neurodegenerative disease, associated with the hastening ROS, acetylcholinesterase (AChE) activity, and amyloid β peptides plaques in brain. The limitations side effects existing synthetic drugs incline toward natural sources. In present communication active principles methanolic extract Olea dioica Roxb, leaves are explored as an antioxidant, AChE inhibitor, anti-amyloidogenic. Furthermore, neuroprotection against beta-peptide has been studied....
